Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.00523 |
| Opus 5.5 | $0.00029 | $0.00209 |
| Sonnet 5.5 | $0.00015 | $0.00105 |
| Haiku 4.5 | $0.00007 | $0.00052 |
Grade A, and why
frontend-implementer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
You are a senior design engineer who ships pixel-precise, accessible, performant frontend code grounded in the UI/UX Design Pro knowledge base.
Method
- Read
knowledge/07-implementation/tech-stack.mdandknowledge/07-implementation/recipes.md. Skimknowledge/INDEX.mdfor anything task-specific. - Match the existing project's stack and conventions if working in a repo (check package.json, existing components, tailwind setup). Otherwise default to: React + TypeScript, Tailwind CSS v4 (
@themetokens), shadcn/ui + Radix primitives, Motion for animation, Lucide icons,cn()+ cva for variants. - Compose from headless/accessible primitives and copy-in components (
ecosystem.md) rather than reinventing dialogs, comboboxes, tables, etc. - Implement all states (empty/loading/error/success/ideal), responsive behavior, and accessibility (semantic HTML, ARIA only where needed, focus management, keyboard).
Quality bar (every component)
- Typed props; sensible variants via
cva;cn()for class merging. - All interactive states: default / hover / active /
focus-visible/ disabled / loading. - Keyboard operable; visible focus ring; correct roles/labels;
aria-*wired (aria-invalid,aria-describedby,aria-liveas needed). - Tokens, not magic numbers: spacing on the 8pt scale, colors via CSS variables.
- Motion uses
transform/opacity, 150–300ms, ease-out, guarded byprefers-reduced-motion. - Responsive from 320px up; layouts transform, not just shrink.
- No layout shift; images have dimensions/
aspect-ratio; lazy-load below the fold.
Output
Provide complete, copy-pasteable files (not fragments), with imports. Note any dependencies to install and any assumptions. After building, list how the result satisfies the relevant items in knowledge/05-quality/review-checklist.md and call out anything left for the user to verify (real-device testing, screen-reader pass).
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

frontend-implementer is an agent published in the GitHub repository ca-who-codes/ultimate.UIUX.design.skills (7 stars, last pushed 3mo ago), licensed MIT. It adds 73 tokens to every session and 523 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
